Photocatalysis is the most promising green approach to solve antibiotic pollution in water, but actual treatment effect limited by photocatalytic activity. Herein, Bi and BiOCl were loaded onto surface of Ce-MOF (metal–organic framework) using an electrostatic adsorption method, a special ternary heterojunction Ce/Bi/BiOCl was successfully prepared as photocatalyst for degradation tetracycline (TC). FTIR demonstrated that obtained contains functional groups such -COOH belonging characteristic crystal planes BiOCl, indicating successful construction photocatalyst. The results UV–vis absorption spectra confirm band gap reduced from 3.35 eV 2.7 eV, resulting enhanced light capability visible region. constructed Ce-MOF, Bi, could achieve narrow reasonable structure, thereby enhancing separation photogenerated charges. Consequently, performance significantly compared BiOCl. Therefore, can rate 97.7% within 20 min, which much better than (14.8%) (67.9%). This work MOF-based photocatalysts revealed relationship between heterojunctions provides inspiration constructing other heterogeneous catalysts use field photocatalysis.

The increasing concentration of antibiotics in natural water poses a significant threat to society’s sustainable development due pollution. Photocatalytic technology is an efficient and environmentally friendly approach environmental purification, offering great potential for addressing pollution attracting attention from scholars worldwide. TiO2, as representative semiconductor photocatalytic material, exhibits strong oxidation ability excellent biocompatibility. However, its wide band gap the rapid recombination photo-generated electron–hole pairs significantly limit applications. Recent studies indicate that constructing heterojunctions with synergistic plasmonic effects effective strategy developing high-performance photocatalysts. In this study, Bi metal nanoparticles (BiO)2CO3 nanosheets were simultaneously grown on TiO2 nanofibers via situ hydrothermal method, successfully forming Bi@(BiO)2CO3/TiO2 composite fiber photocatalyst effects. surface plasmon resonance (SPR) effect combined (BiO)2CO3/TiO2 heterojunction enhances sunlight absorption, facilitates separation carriers, strengthens photo-oxidation reduction abilities. This system effectively generates abundant hydroxyl (·OH) superoxide (·O2−) radicals under excitation. Consequently, exhibited outstanding performance. Under simulated 60 min, photodegradation efficiencies quinolone lomefloxacin, ciprofloxacin, norfloxacin reached 93.2%, 97.5%, 100%, respectively. also demonstrates stability reusability. study represents step toward application TiO2-based materials purification.
